This study aimed to examine the types and characteristics of otorhinolaryngology examinations performed by clinical laboratory technologists and to investigate the working environment and scope of work of otorhinolaryngology laboratory personnel using online questionnaires. Based on the research results, constructive policy measures for the University-Association-Society were also presented. Most of the survey respondents were in their 40s (34.1%). Females accounted for 80.2% of respondents and 30.8% of them had a career spanning 15 years or more. We found that laboratory personnel had a wide scope of work, high work stress and frequently suffered occupational diseases. We observed that, to reduce stress and increase satisfaction, an expansion of the workforce was necessary. Compared to other occupations, 72% of clinical laboratory technologists occupied more senior positions, occupational distribution depended on senior positions (P<0.001). Clinical laboratory technologists performed about 26 types of otorhinolaryngology examinations. The most frequent test performed daily was pure tone audiometry, and polysomnography took the longest test time, with an average of 8 hours. In conclusion, clinical laboratory technologists were in charge of various specialized otorhinolaryngology examinations. Considering the importance of clinical laboratory technologists in otorhinolaryngology, the University-Association-Society should put in additional effort into nurturing otorhinolaryngology examination experts.
[가솔린엔진부문] 소형 2STROKE 기관의 PISTON PIN의 최적설계에 관한 연구
김영희(Younghoi Kim),정진석(Jinseok Choung) 한국자동차공학회 2000 한국자동차공학회 춘 추계 학술대회 논문집 Vol.- No.-
To be considered the contact surface of pin and piston importantly as design a piston pin. Especially the 2 stroke engine RPM for 2 wheel vehicle is much higher than 4 stroke engine for 4wheel vehicle and it's at a disadvantage that cooling and lubrication ability. So it is easy to be wore that inner diameter of piston pin hole and outer diameter of pin. Therefore the wear endurance of a pin must be considered sufficiently when design a piston pin.<br/> In this paper, we will report the relation of wear of pin outer diameter, shape, heat and<br/> surface treatment.<br/> We will analyze that the relation that elongation and stress of pin with measuring the degree of wear after endurance test which exchange of shape, heat and surface treatment on real engine and that the elongation and stress with! CAE analysis which each shape of pin.<br/>

안과검안인력의 근무 환경 및 업무 범위에 대한 연구는 보고된 바 없다. 우리는 온라인 설문 조사를 이용하여 이러한 점들을 조사하였다. 또한, 연구 결과를 토대로 임상병리사 관점에서 대학-협회-학회에 정책 방안을 제안하고자 하였다. 대상자의 연령은 20대가 40.7%로 가장 많았고, 30대(28.4%), 40대(23.5%), 50대(7.4%) 순이었다. 대상자의 56.0%가 여성이었으며, 임상 경력은 1년 미만에서 15년 이상까지 고르게 분포되어 있었다. 안과검안인력의 업무 스트레스는 높았고, 직업병은빈번하였으며, 업무 범위는 넓은 것으로 나타났다. 업무 스트레스를 줄이고 만족도를 높이기 위한 최적의 방안은 인력 확충이었다. 검사실 내 임상병리사가 선임 직종인 경우는 48%로 다른 직종에 비해 높았고, 검사실 내 직종 분포는 선임의 직종과 밀접한 관련이 있었다(P<0.001). 임상병리사는 약 30가지의 안과검사를 담당하고 있었다. 하루에 가장 많이 시행되는 검사는 굴절검사였으며, 색각경검사가 27분으로 가장 긴 소요시간을 보였다. 종합하면, 임상병리사는 매우 다양한 안과 검사를 수행한다. 검안에서 임상병리사의 중요성을 감안할 때 대학-협회-학회 차원의 다각적인 노력이 요구된다.
